9. Incremental Measuring Systems Operation

10. Working principle It is based on a grated design disc, in other words a transparent disc of glass where a radial grating of lines and gaps forming an incremental track is printed. The disc is penetrated by a light beam generated by a light source, partially obscurated by a scanning reticle with four additional grated fields. These four fields are also penetrated by the light beam. During the disc movement they produce four phase-shifted beams. Each beam is phase shifted of half – disc line from the other. ROTAPULS Incremental encoders

11. Working principle The modulation index of each light beam is sensed by photo-elements placed on the opposite side of the disc. The photo-elements transform the entering light signals in four sinusoidal current signals. PHOTO-ELECTRONIC READING DIGITIZING POWER OUT POWER SUPPLY +3,3V +Vdc The analogue signals are digitized and multiplied by one interpolation circuit Furtherly they are sent to amplification circuits to be conveniently powered in output ROTAPULS Incremental encoders

12. AB channels = Bidirectional (speed and rotation sense detection) AB0 = Bidirectional + Zero /A, /B, /0 = Complementary signals (inverted) Output signals

13. ROTAPULS Incremental encoders 1Vpp output circuit Sin/cos analogue signals for external interpolation Output signals

14. Methods for signals transmission “ Normal ” = 1 signal each channel (AB0) connection to Push-Pull, NPN, PNP devices Needs external filters for noise reduction “ Complementary ” = additional inverted signal for each channel (A B 0 + /A /B /0) safe transmission even with long cables and noisy environment ROTAPULS Incremental encoders

15. Manipulation of signals Quadrature of signals (x4) Reading all signal fronts (A+B), resolution increases 4 times ex. 500 PPR = 2000 fronts Interpolation SIN/COS output signals can be interpolated Interpolation “ divides ” a sine/cosine signal into many pulses ex. 1024 sin/cos x10 = 10240 fronts ROTAPULS Incremental encoders
